Give your bio a proper home
Instagram gives you one link. A Liite page at liite.co/yourname holds the rest: your links, social icons, a WhatsApp button and a real heading in a theme you pick, with no symbols needed.
Bold text generator: what to know
This page starts the instagram fonts generator for this case. For every option and how to use it, see the instagram fonts generator.
Sans bold or serif bold?
Sans bold looks like the app's own text, only heavier, so it reads as a heading. Serif bold has small feet on the letters and stands out more, which suits a name or a single word.
Bold italic and bold script are for decoration. Use them for one or two words, not a whole line.
Where bold helps
Use bold to mark a heading inside a long caption or post, like "What's included" or "Dates". Readers scanning on a phone find the part they need faster.
Don't bold whole paragraphs, hashtags or anything people might search for, such as a product or place name. Search treats the bold letters as different characters.
Questions
How do I make my text bold?
Type it in the box, press copy next to Sans bold or Bold, and paste it into your post. It stays bold because the letters themselves are bold characters.
Can I make bold text blue or another colour?
Not with copied text. The app picks the colour, and plain text and bold Unicode letters get the same one. Only an app's own text tool, such as Instagram Stories, lets you colour text.
Does bold text work on Facebook?
Yes. The bold letters paste into Facebook posts, comments and your profile like any other text. Check it on your phone before posting, as some older devices lack these characters.
